UI Automation with White issue finding childs

Question

For some reason I am getting a run-time error from White.Core when trying to locate a Window child from its parent.

ERROR displayed:

White.Core.Mappings.ControlDictionaryException: Could not find TestControl for ControlType=window and FrameworkId:Win32

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

The current structure that I am trying to navigate is the following:

Main Window->Panel->Window

and I am using the following method in C#

        public Boolean wasUserLoggedIn(string id1, string id2)
    {
        Thread.Sleep(500);
        var mdiClient = window.MdiChild(SearchCriteria.ByControlType(ControlType.Pane).AndAutomationId(id1));
        Thread.Sleep(500);
        var selectPatient = (Window)mdiClient.Get(SearchCriteria.ByControlType(ControlType.Window).AndAutomationId(id2));
        Thread.Sleep(500);
        return selectPatient != null? true: false;
    }

and calling the method as follow:

Boolean wasFound = wasUserLoggedIn("40960", "40961");

UIspy objects used for identify ControlType and AutomationID:

AutomationId: 40960
ControlType: ControlType.Pane
Name: 
HelpText: 
Bounding rectangle: 8,78,900,581
ClassName: MDIClient
IsOffScreen: False
FrameworkId: Win32
ProcessId: 5964


AutomationId: 40961
ControlType: ControlType.Window
Name: Home
HelpText: 
Bounding rectangle: 8,59,900,600
ClassName: ClaWin01000000H_2
IsOffScreen: False
FrameworkId: Win32
ProcessId: 5964

Solution

I recommend upgrading to TestStack.White rather than the old White library.

The problem is that you are not supposed to use .Get() to resolve windows. For MDI applications you should use MdiChild(), if it is a modal window, use .ModalWindow() on the parent window or go back to the application then use Window() to get the window.

Hope that helps

OTHER TIPS

Is the Pane a descendant of the Window AutomationElement? The Window you're trying to find might not be in focus.
